[Interest] Tweaking a static build of Qt 6 for Windows

[Cristian Adam]

Hi,

All the missing __imp symbols mean that you are trying to link to a shared library.

C:\Projects\Qt\repo\qtbase
$ configure --help | findstr static
                         sections. [auto for static builds, otherwise no]
  -static .............. Build static Qt libraries [no] (yes for UIKit)
  -static-runtime ...... With -static, use static runtime [no] (Windows only)
                         benchmarks, manual-tests, minimal-static-tests)

Make sure you pass both -static and -static-runtime to your Qt configuration. -static-runtime will get you /MT for cl.exe

Cheers,
Cristian.

Thiago,

Right now my problem is that the static build of Qt is unable to compile successfully my project and I don’t understand why.

The static build of Qt does not have this problem on Mac.

Any ideas?

Thanks!

Best,

Nuno
